P @ Q & R # S
Understanding Blood Relations using Symbols
This question asks us to decipher relationships represented by symbols and find which symbolic expression translates to "P is the father-in-law of S". We are given the following definitions:
- A @ B means A is the husband of B. This tells us A is male and B is female.
- A & B means A is the mother of B. This tells us A is female.
- A # B means A is the wife of B. This tells us A is female and B is male.
We need to find the option that represents the relationship where P is the father-in-law of S. The term "father-in-law" means the father of one's spouse. So, we are looking for a relationship string where P is the father of the person S is married to, or P is the father of the person who is married to S.
Let's analyse each option provided:
Analyzing Option 1: P @ Q & S # R
- P @ Q: P is the husband of Q. This means P is male, Q is female.
- Q & S: Q is the mother of S. This means Q is female.
- S # R: S is the wife of R. This means S is female, R is male.
Combining these: P is the husband of Q, and Q is the mother of S. Since P is Q's husband, P is the father of S. Also, S is the wife of R. So, P is the father of S, and S is married to R. This makes P the father-in-law of R (father of R's wife), not S.
Analyzing Option 2: Q @ P & R # S
- Q @ P: Q is the husband of P. This means Q is male, P is female.
- P & R: P is the mother of R. This means P is female.
- R # S: R is the wife of S. This means R is female, S is male.
Combining these: Q is the husband of P, and P is the mother of R. Since Q is P's husband, Q is the father of R. Also, R is the wife of S. So, Q is the father of R, and R is married to S. This makes Q the father-in-law of S (father of S's wife). This option does not mean P is the father-in-law of S.
Analyzing Option 3: P @ Q & R # S
- P @ Q: P is the husband of Q. This means P is male, Q is female.
- Q & R: Q is the mother of R. This means Q is female.
- R # S: R is the wife of S. This means R is female, S is male.
Combining these: P is the husband of Q, and Q is the mother of R. Since P is Q's husband, P is the father of R. Also, R is the wife of S. So, P is the father of R, and R is married to S. This means P is the father of S's wife (R). Therefore, P is the father-in-law of S. This option matches the required relationship.
Analyzing Option 4: P @ Q & R & S
- P @ Q: P is the husband of Q. This means P is male, Q is female.
- Q & R: Q is the mother of R. This means Q is female.
- R & S: R is the mother of S. This means R is female.
Combining these: P is the husband of Q, and Q is the mother of R. Since P is Q's husband, P is the father of R. Also, R is the mother of S. This means P is the father of R, and R is the mother of S. This makes P the paternal grandfather of S. This option does not mean P is the father-in-law of S.
Based on the analysis of all options, the expression P @ Q & R # S correctly signifies that P is the father-in-law of S.
Summary of Relationships
| Option | Expression | Derived Relationships | Relation of P to S |
|---|---|---|---|
| 1 | P @ Q & S # R | P is husband of Q; Q is mother of S; S is wife of R. | P is father of S. (Also P is father-in-law of R) |
| 2 | Q @ P & R # S | Q is husband of P; P is mother of R; R is wife of S. | P is mother of R. (Q is father-in-law of S) |
| 3 | P @ Q & R # S | P is husband of Q; Q is mother of R; R is wife of S. | P is father of R. R is wife of S. ⇒ P is father-in-law of S |
| 4 | P @ Q & R & S | P is husband of Q; Q is mother of R; R is mother of S. | P is father of R. R is mother of S. ⇒ P is paternal grandfather of S |
Conclusion
Option 3, P @ Q & R # S, correctly establishes the relationship where P is the father-in-law of S.

Additional Information: Solving Blood Relation Puzzles
Blood relation questions often involve decoding relationships based on symbolic representations or descriptive sentences. Here are some tips for solving them:
- Identify the relationships each symbol or phrase represents clearly.
- Note down the gender implications for each relationship if provided (e.g., husband means male, wife means female, mother means female).
- Break down the given expression or statement into smaller relationship segments.
- Combine the segments step-by-step, building a family tree or diagram if helpful.
- Keep track of the gender of individuals as you build the relationships, as this can eliminate possibilities.
- For multiple-choice questions, test each option against the target relationship.
- Understand the definitions of common relationships like father-in-law, brother-in-law, paternal/maternal grandparent, etc.
